SecurityError: Error #2122: Security sandbox violation

[panel]

Hi

I have issue with loading images

This works

var loader:Loader = new Loader();
loader.load(new URLRequest("http://l.yimg.com/www.flickr.com/images/tour/hp_1.jpg"));
loader.contentLoaderInfo.addEventListener(Event.INIT, onInit);

function onInit(evt:Event):void
{
    addChild(loader)
}

Here is sample
http://oceanic.wsisiz.edu.pl/~hamela/Igor/NoBitmap.html

This Do Not Work
If I try to make any changes to image like this

var loader:Loader = new Loader();
loader.load(new URLRequest("http://l.yimg.com/www.flickr.com/images/tour/hp_1.jpg"));
loader.contentLoaderInfo.addEventListener(Event.INIT, onInit);

function onInit(evt:Event):void
{
    var bitmap:Bitmap = (evt.target.content);
    if (bitmap != null) 
    {
        bitmap.smoothing = true;
    }
    addChild(bitmap);
}

error appears in debug version of FlashPlayer and image never appears ;/

SecurityError: Error #2122: Security sandbox violation: LoaderInfo.content: http://oceanic.wsisiz.edu.pl/~hamela/Igor/Bitmap.swf cannot access http://l.yimg.com/www.flickr.com/images/tour/hp_1.jpg. A policy file is required, but the checkPolicyFile flag was not set when this media was loaded.

You want to use a LoaderContext when loading, to ensure manipulation outside of the local sandbox..

look up the LoaderContext class, and use it as the 2nd argument in the load() function

Oki dit is and worked

but there is another issue

I am loading images from

[url]www.i.myDomain.com/Image1.jpg[/url]

and now it wants to load crossdomain xml from

[url]www.i.myDomain.com/crossdomain.xml[/url]

Unfortunetly it isn't imposible to put crossdomain file there, becouse this url is created at cahce proxy level, and it's kind of vistual url.

Is there any way to change crossdomain.xml path?
ex for

[url]www.abc.myDomain.com/crossdomain.xml[/url]

Security.loadPolicyFile(url)
